Script to generate env file for bluesky pds.

To make a pds at example.com with user handles at *.example.com:

```sh
./mkpdsenv.sh example.com
```

To make a pds at pds.example.com with user handles at *.example.com:

```sh
./mkpdsenv.sh pds.example.com -u .example.com
```

Script creates file named pds.env and then you are ready to run a pds:

```sh
docker run -d --name=pds --restart=unless-stopped -v "./data:/data" --env-file=pds.env -p 3000:3000 ghcr.io/bluesky-social/pds:latest
```

After connecting domain and reverse proxy you can create an account with `./pdsadmin.sh account create` and you are finished.

Remember you must delete and recreate the container to apply changes made to the env file.
